Clamp aligned_offset in MemorySnapshotSanitized

MemorySanitizer::Sanitize() computes the number of leading unaligned
bytes from the snapshot's base address and uses it as the length of a
memcpy into the data buffer and as the subtrahend for the word count.
When the snapshot is shorter than the alignment offset (an unaligned
base address with a sub-word region), the leading memcpy writes past the
end of the buffer and the word count underflows.

Clamp the offset to the buffer size so that short unaligned regions are
defaced in place.

Add MemorySnapshotSanitized.ShortUnalignedRegion64/32 unit tests
covering every (offset, size) pair below the pointer width.
